Caroline learned another four-ring magic, used the plane grown by magic as a front-mounted vehicle, and flew to a high altitude in a circle.
There is no problem with the knowledge taught by His Highness Li Xiang, but it is indeed difficult to breathe at high altitudes.
At this stage, the various tasks of the institute are not too heavy. Caroline suddenly thought of going to high altitude because a new project recently came in, requiring the development of a magic-based carbon dioxide filter.
The projects received by the institute all come through formal channels from higher-level departments. There will not only be one requirement, but also various additional details and related reference books.
According to the project description, there are no specific size requirements for the early models of carbon dioxide filters, but it is necessary to ensure that the ventilation systems and equipment rooms of each shelter can be inserted into them.
It's a very simple project, but I always feel like I'm looking down on people.
Only when you really do it will you realize how much trouble there is.
Caroline initially planned to directly use magic to carry out qualitative changes. After understanding the conditions for decarbonization of carbon dioxide, it is not difficult to use magic to filter it. There is a ready-made spell in the explorer professional magic to improve the gas environment in ruins and crypts.
The samples were quickly produced and put into the underground shelter of Xincheng Station for testing. Then a problem arose.
The underground part of Xincheng Station is usually used for passengers to board the northbound platform. There are no passenger trains at night, so it will not be used.
The test results of the first version of the prototype during the day were very unsatisfactory. During the gas sampling for a few hours before and after, the carbon dioxide content did not decrease significantly at four of the ten testing points, and kept fluctuating around 2‰.
The carbon dioxide content of 2‰ does not seem to be high, but when there is no prototype, the underground area of the station passes through two ventilation shafts that pass between the two railway tracks. It is usually only 2‰, which means that the prototype has no effect at all in some areas.
Referring to the data, the outdoor carbon dioxide content is 0.4‰ to 0.7‰, and the "good" air standard in subway stations is about 1‰, which in parts per million is 400 or 1,000. The underground part of Xincheng Station is worse than the subway, mainly due to the lack of small mechanical ventilation equipment. It is installed, but it is used to cope with ultra-high population density, the power is relatively large, and it is rarely started during non-evacuation periods.
In the night experiment, due to the stable gas environment, carbon dioxide deposition will cause the average content to increase compared with the daytime, but the effect of the prototype at this time is obviously better than during the day.
In short, the spells proved useful, but a simple spell casting point seemed unable to cope with situations where there was a lot of personnel activity.
Caroline has been playing around in the sky, and she already knows what they are worried about above, and she is more concerned about it.
He took the team members to various cities to ask for construction drawings of shelters, including the Wangtingshu shelter. After returning, he worked hard for a while and came up with a new plan.
To briefly describe the new solution, it is to use ventilation ducts to introduce airflow from one end, filter the carbon dioxide and then discharge it from the other pipe. Of course, there are many ventilation ducts in large shelters, so the actual situation is more complicated.
After the application is submitted, the experimental reconstruction of the New City shelter will be approved by the Engineering Department of the Ministry of Industry, coordinated by the Ministry of Industry.
If another academician were to do it, the approval of this modification would probably be delayed by another version. However, Caroline used her thoughts to think more comprehensively. The ventilation entrance was chosen lower on the side wall, and she did not propose to embed it into the wall. It was not necessary. Changing the walls and floors makes it easier to coordinate.
The space of large-scale civil air defense facilities is large enough, and several square metal pipes are exposed without affecting its use.
Surface piping construction is also relatively fast. The main ventilation pipeline and the minimum number of branches for testing were built in just ten days.
The main ventilation pipes are two large pipes fixed on the ceiling. There are currently only six branches, three for intake and three for outlet.
After completion, the utility room that originally stored cleaning tools was used as the equipment room, and the door was changed to a closed type, entering the second round of testing.
The effect of this version is much better. The maximum carbon dioxide concentration measured at multiple points after half an hour of being turned on was only 0.8‰, and it was maintained stable enough.
But still worried, a temporary evacuation drill was organized after coordination.
The scale is small, with only 3,000 people. The main personnel are those responsible for organizing the people during the actual evacuation, as well as some municipal personnel.
The actual time underground is four hours, of which two hours the ventilation shaft and passage door are completely closed, and magic personnel are inside to prevent accidents.
After a few days of busy work, I got the high-density sampling data at each point in these four hours, and I finally had a real basis.
The worry above is that one day in the future it will be completely impossible to breathe outside. This carbon dioxide filter device is a very important life support equipment. While ensuring the filtration capacity, it must also have high enough reliability and maintainability.
Only by using the closed experimental data to obtain the per capita carbon dioxide production can the specific number of people be marked.
For example, if a single set of equipment has 3,000 people, the number can be stacked according to the size of each shelter, and a certain proportion of spare machines are reserved to ensure air quality during maintenance.
At this step, it enters the finalization stage. In addition to the body of the magic carbon depositor, the standards for the entire set of pipelines must also be given.
The piping standards also involved other things, and Caroline arranged them as well, adding an air flow display function to the carbon depositor body. With the flow display, the construction personnel can decide independently whether to use the weak wind spell of the carbon precipitator to use a large low-wind speed self-flow pipe, or to install a small pipe with a fan.
Two sets of the third version were made and turned in. A bonus will be awarded one month later, and there is also a special reward.
Dean Xiu personally awarded a special award, a second-class Phoenix Medal!
"It seems that your Majesty has been alarmed. Well done! He is indeed our most powerful academician!"
Even though she had become more confident, Caroline still blushed a little when the dean praised her. "It's not that powerful. I just wish I could help."
The dean encouraged her with a few more words and let her go out. The outside was already blocked by other academicians and researchers:
"Caroline, have you really received the second-class Phoenix Medal? You won't be the first one to get it, right?"
Although His Majesty did not personally award the medal, as a sign of importance, three inner court guards escorted the medal to the dean. One person walked forward holding the box in both hands, which was too conspicuous.
Of course, even if it looks like a medal box, it is not evidence of the contents of the box. The inner court guards did not answer when asked, but the people in the courtyard are not stupid. The manufacturing bureau of the carbon precipitator named "Spring Breeze" has a mass production license, and The inner court guards almost arrived with front and rear feet. Then I went to the finance department to inquire, and found out that Caroline's bonus had just been reported to the finance department, but the hospital had just settled the accounts, and the money was paid by other departments.
The treasurer also secretly said, "Caroline is going to donate money again," indicating that the amount of money may be much larger than the hospital's limit.
Putting these clues together, I could tell with the soles of my feet that there was probably a medal in the box.
The Phoenix Medal and the War Bear Medal will not be awarded repeatedly. The institute does not have a War Bear in the civilian system. Caroline already has a third-class medal, so it can only be a second-class Phoenix Medal.
Caroline hadn't looked at it carefully at this time, so she tried to deal with it: "It's definitely not the first one, so stop crowding."
"Let's take a look, we haven't seen the entity yet."
The medals are made by heavy craftsmen, and the people at the institute are only responsible for a small part of the enchanting work, so they have never seen the complete version. It is possible to get it by just thinking about it, but such rare things are not as enjoyable as seeing them in person.
Caroline glanced around, then opened the box she was holding with the mouth facing outward.
The dark gray tungsten alloy base is embedded with a silver phoenix wrapped in a hexagonal gold frame, with ribbons and large pin buckles on the left and right.
"These three colors look pretty good together."
"Let's take a look at the one below!" Someone shouted. Those who knew this skill were obviously those who had received medals.
The medal box has two layers. The upper one is for daily wear, and the lower one is the real medal. Of course, the body of the two is the same, but the frame and enchantment are different. The frame of the real medal is pure gold, which can be picked out with your fingernails. mark. In terms of enchantment, it is an additional daily healing spell. The body enchantment is self-cleaning. The enchantment cannot replenish the magic power by itself. The mage can charge it through the air.
Caroline quit and closed the box.
Many people who have received medals in the past have been fooled and used their hands to touch the gold frame.
It is real pure gold, something that can be pulled out of shape by hand. After punching and cutting, it is polished by Metro Heavy Industries' best machine. When you touch it with your hands, even a little force may leave permanent marks, not to mention rubbing it on clothes. of.
I don’t even have to change it if I get scratched, and there’s no place to cry.
Caroline squeezed out of the crowd and took the medal back to her hut, then opened the box, lifted out the top layer, took a look at the bottom, and her eyes turned into crescents with a smile.
Without looking too much, I put the upper layer back, took out the daily seal inside, and looked behind it.
005, a lot of third-class medals were issued. Everyone knows that medals do not have the number 4, and all the digits do not contain 4, so she was the fourth to get it.
Two of them were probably taken by the two generals of the garrison. Who has the other piece?
